V = pi(r)^2(h)
Answer with pi substitute (3.14):
4 * 4 = 16
3.14 * 16 * 4
V = 200.96
Answer without pi substitute:
4 * 4 = 16
v = pi(16)(4)
v = 64pi
Answer:
- X Greater-than-or-equal-to 12
- A closed circle is used on the graph.
- The arrow on the graph points right.
Step-by-step explanation:
This one-step inequality can be solved by adding the opposite of the constant that is added to x. A number line graph of the solution is attached.
x -2.6 ≥ 9.4
x ≥ 12.0 . . . . . . add 2.6 to both sides
The "greater than" relation means that numbers larger than 12 will be included in the solution set. Shading of the number line will be to the right of 12.
The "or equal to" relation means that 12 itself is included in the solution set. This is indicated by a closed circle at 12 on the graph.
The true statements are ...
- X Greater-than-or-equal-to 12
- A closed circle is used on the graph.
- The arrow on the graph points right.
Answer:
k = 5
Step-by-step explanation:
The given line is y = 4x - 14.
The given point is (k, k + 1).
For this point, x = k and y = k + 1.
You substitute these equations into the line's equation to find the value of k.
(x = k)
(y = k + 1)
y = 4x - 14
(k + 1) = 4(k) - 14
Solve for k.
k + 1 = 4k - 14
Subtract k from both sides.
1 = 3k - 14
Add 14 to both sides.
15 = 3k
Divide both sides by 3.
15/3 = k
Simplify.
5 = k
And that's the answer!
